Added support for reading and writing Multichannel Broadcast wave format (.WAV) a.k.a. EBU RF64. This is an extension to the Broadcast wave format (which is in turn based on the normal Microsoft wave format). It adds features to support for file sizes > 4 GB, as well as for high bit-depth and multi-channel audio.

Added support for reading and writing WavPack (.WV) lossless compressed files. NB; to use this you need to install the free WavPack codec add-on (wavpackdll.dll).
